Answer:
The method is as follows:
double square(int num){
return num*num;
}
Explanation:
Written in C++
This first line defines the method
double square(int num){
This line returns the square of num

A constructor, member initialization lists and also the default member initializer. Here you see all three (in reality you choose one construct per variable).
class A
{
public:
int x = 0;
A() : x(1)
{
x = 2;
}
};
Answer:
Explanation:
Let G denote an unambiguous Grammar capable of producing simple mathematical expressions, involving operators +,-,*,/. These operators are left associative (which ensures left to right evaluation). S is the start symbol of the Grammar i.e. the production starts from S. n denotes a number and is a terminal i.e. we can't produce anything further from n. Then, the solution is as follows :
S → S + T |S - T | S
T→T | F | T*F|F
F → n
Here, S, T and F are variables. Note that /,* have been given precedence over +,-.
Answer:
The right answer is: Option 3: RFID
Explanation:
One of the latest technologies is RFID. RFID stands for radio frequency identification. It is a fast and new technology that can be used for tagging goods in store. It is used to identify tags put on an object using electromagnetic fields.
Hence,
The right answer is: Option 3: RFID
The above command allows any interface to learn its IP address dynamically by using the DHCP protocol. It is best suited for Ethernet interfaces that dynamically connect to an ISP.
It also in the majority of cases configures the switch to acquire an IP from a DHCP server. Once one inputs this command, it contains a discover message that includes the MAC address of the ethernet interface and the default hostname of the router.
